Santa Marta Landfill Gas (LFG) Capture for Electricity Generation Project
The Big Picture:
Landfill gas generators use the methane that is produced by the decomposition of organic materials in existing landfills to produce clean, renewable electricity. The process removes harmful methane from the environment. Methane is a powerful green house gas that is 28-36 more potent than CO2 over a 100 year lifespan.
How It Works:
Landfills produce gas when organic materials in the facilities naturally decompose. This creates a steady flow of natural gas over many years and can power generators to produce renewable electric power (link to Wikipedia)
The Santa Marta landfill is 700 acres in size and receives roughly 1.3 million metric tons of waste every year. The resulting LFG produces 28 MW of renewable energy into the regional grid. Located just outside Santiago city it became operational in2002. It is one of the most important landfills in the region, serving a population of around 1,200,000. This Gold Standard-certified project includes a plan to continuously support local communities through a nursery and day care in Lonquén, as well as investments in schools. The project creates jobs for women at the facilities, and their children use the nursery while the women work.
